Strabo, Geography

Now the voyage from Corocondame is straight towards the east; and at a distance of one hundred and eighty stadia is the Sindic harbor and city; and then, at a distance of four hundred stadia, one comes to Bata, as it is called, a village and harbor, at which place Sinope on the south is thought to lie almost directly opposite this coast, just as Carambis has been referred to as opposite Criumetopon.¹ After Bata Artemidorus² mentions the coast of the Cercetae, with its mooring places and villages, extending thence about eight hundred and fifty stadia; and then the coast of the Achaei, five hundred stadia; and then that of the Heniochi, one thousand; and then Greater Pityus, extending three hundred and sixty stadia to Dioscurias. The more trustworthy historians of the Mithridatic wars name the Achaei first, then the Zygi, then the Heniochi, and then the Cercetae and Moschi and Colchi, and the Phtheirophagi who live above these three peoples, and the Soanes, and other small tribes that live in the neighborhood of the Caucasus. Now at first the coast, as I have said, stretches towards the east and faces the south, but from Bata it gradually takes a turn, and then faces the west and ends at Pityus and Dioscurias; for these places border on the above-mentioned coast of Colchis. After Dioscurias comes the remaining coast of Colchis and the adjacent coast of Trapezus, which makes a considerable bend, and then, extending approximately in a straight line, forms the righthand side of the Pontus, which faces the north. The whole of the coast of the Achaei and of the other peoples as far as Dioscurias and of the places that lie in a straight line towards the south in the interior lie at the foot of the Caucasus.
